Both are installed with plugs in our kitchen too. The possibility is
both having inductive load(motors) it can falsely trigger GFCI sensor
and shut the unit specially when starting. Like wise fridge is not on

There is no requirement that the garbage disposal be GFI protected. If it
is plugged into an outlet under the counter instead of being hardwired, the
outlet would need to be GFI (210.8(A)(7).
The more I think about this I realize that since both units will have
water in them that it makes sense to put on a GFI breaker. (even if not
needed for the disposal)
I plan to do this by direct wiring and not by the use of receptacles.
Originally I was thinking of running two, 15 amp circuits
but think a single 20 Amp should suffice.
Also, not that the codes are real strict here in western NC, neither the
DW or disposal have any type ground fault protection, other than a hard
wired ground. The house was built 5 years ago. It does have arc fault
detection for the bedrooms, though, plus GFCIs for all kitchen, bath,
unfinished basement, and exterior outlets. Also, you'd never want any
protectors on the fridge or freezer for obvious reasons.
